Autism spectrum disorder risk linked to insufficient placental steroid

A study in experimental models suggests that allopregnanolone, one of many hormones produced by the placenta during pregnancy, is so essential to normal fetal brain development that when provision of that hormone decreases or stops abruptly - as occurs with... Continue Reading →

High levels of estrogen in the womb linked to autism

Scientist have identified a link between exposure to high levels of oestrogen sex hormones in the womb and the likelihood of developing autism. The findings are published in the journal Molecular Psychiatry. The discovery adds further evidence to support the prenatal... Continue Reading →

The neuroscience of autism: New clues for how condition begins

UNC School of Medicine scientists unveiled how a particular gene helps organize the scaffolding of brain cells called radial progenitors necessary for the orderly formation of the brain. Previous studies have shown that this gene is mutated in some people... Continue Reading →

Synapses of the reward system at stake in autistic disorders

Autism spectrum disorders are a heterogeneous group of neurodevelopmental disorders, one of the main characteristics of which is impaired social communication. But what happens in patients' brains that disrupts their social skills? According to scientists from the Universities of Geneva... Continue Reading →

How to build a brain: discovery solves evolutionary mystery

Researchers at King’s College London have discovered a fundamental process by which brains are built, which may have profound implications for understanding neurodevelopmental conditions like autism and epilepsy. The study, published in Nature and funded by the Wellcome Trust, also answers an... Continue Reading →

Infections during pregnancy may interfere with key genes associated with autism and prenatal brain development

If a mother picks up an infection during pregnancy, her immune system will kick into action to clear the infection – but this self-defense mechanism may also have a small influence how her child’s brain develops in the womb, in... Continue Reading →
